P 42,194 Int. Cl. B65h 75/28; B65d 85/67 US. Cl. 20658 6 Claims ABSTRACTOF THE DISCLOSURE A toilet paper roll and method of making sameaccording to which the outer end of the toilet paper web is connected tothe nearest toilet paper web winding therebelow by means of a thread,band or the like.

The present invention relates to a toilet paper roll comprising one ormore layers of paper, in which the end of the outer layer is connectedwith the nearest inner paper layer or layers. The present inventionfurthermore concerns a method of producing a toilet paper roll of thistype.

With heretofore known toilet paper rolls, the outer end of the outerpaper layer is connected by an adhesive to the nearest inner paperlayer. With such an arrangement it frequently occurs that the adhesivepenetrates the next inner paper layer and that additional windings ofthe toilet paper are provided with an adhesive. Therefore, if a personstarts to use such toilet paper roll, it is necessary that the end ofthe paper web be taken off from the next inner winding. As a result, inmost instances the inner winding tears so that the use of the end of thepaper roll is affected and a portion of the end of the toilet paper rollbecomes unusable. The situation is even worse when the adhesive by meansof which the end of the paper web is connected to the next inner windingpenetrates a plurality of windings.

With toilet paper rolls comprising a two-layer paper web, the securingof the end of both paper layers requires particular steps which consistsprimarily in that the end of one paper layer is connected with thenearest inner winding by gluing whereupon the outer paper layer, inturn, is to be glued to the next inner winding or the parallel paperlayers. The opening of the paper roll is effected correspondingly in anawkward manner.

It is, therefore, an object of the present invention to provide a toiletpaper roll of the above-mentioned general type which will overcome theabove-outlined drawbacks.

It is another object of this invention to provide a toilet paper roll asset forth above, which will not have an adhesive seam at the end of thepaper web and of the next nearest inner winding.

It is still another object of this invention to provide a paper roll asset forth in the preceding paragraphs which can be produced by machinesin an inexpensive and simple manner.

These and other objects and advantages of the invention will appear moreclearly from the following specification in connection with theaccompanying drawing, in which:

FIGURE 1 diagrammatically illustrates a toilet paper roll which has thewidth of a plurality of normal toilet paper rolls;

FIGURE 2 shows the position of a thread or cord wound around the widepaper roll of FIGURE 1 and also indicates the lines along which the widepaper roll is to be cut to paper rolls of normal size; and

3,469,683 Patented Sept. 30, 1969 FIGURE 3 shows an individual toiletpaper roll according to the present invention.

The toilet paper roll according to the present invention ischaracterized primarily in that a thread, string or band is placed overthe paper end and the next inner winding and is glued to said two parts,said thread, string or band being detachable from said roller withoutdamaging the same. Preferably, the thread, string or band is made ofwater soluble material as, for instance, polyvinyl alcohol or methylcellulose or polyethylene oxide. Also, the adhesive connecting thethread, string or band to the toilet paper roll may consist of a watersoluble glue with low water content mainly on a starch jelly basis.

It is of particular advantage to place the thread, string or bandcentrally around the roller.

According to the method of producing a toilet paper roll of theabove-mentioned type, an adhesive covered string or band is spirallywound upon a toilet paper roll having the width of a plurality of toiletpaper rolls of normal width. This spiral winding of the thread, string Ior band is such that at least approximately a full winding,

' i.e. of 360 extends around the length of a roll section the wide paperroll in such a manner that the thread,

string or band will cross the end of the paper web of the normal widthof a paper roll at about half the width of the paper roll. However, ifit is particularly advantageous for packing the individual rolls, thecrossing of the end of the paper web by the thread, string or band maybe effected at the end of the normal width of an individual roll.

Referring now to the drawings in detail, the paper roll 1 shown in FIG.1 comprises a core 1a of cardboard or the like in the form of a cylinderor a tube and a paper web wound around said core, the end 2 of saidpaper web being located on the next inner winding 3. The edge 4 of thepaper web end is parallel to the longitudinal axis of the roll 1 whichlatter has a width amounting to a plurality of the width of a normaltoilet paper roll. Such wide paper rolls for the manufacture ofindividual toilet papers are known.

For purposes of connecting the end 2 of the paper web to the next innerwinding 3, a string, thread or band 5 is spirally wound around saidpaper roll 1. This thread, string or band 5 is connected to the end 2 ofthe paper web and to the next inner winding 3 by means of a glue oradhesive which is preferably water soluble. Preferably also, the thread,string or band 5 is water soluble.

The spiral windings of the thread, string or band 5 placed around theroller 1 are so arranged that at least one approximately completewinding, i.e. a winding over 360 extends over the width, which widthcorresponds to the width of a normal toilet paper roll as it will be outlater from the roll 1. Thus, the paper roll 1 has a plurality of numbersof thread, string or band windings which correspond to the number ofindividual rolls into which the paper roll 1 will be cut by cutsexecuted in the direction of the arrows 6.

After the paper roll 1 has been cut into individual rolls 7, eachindividual roll will have the shape illustrated in FIG. 3 with thethread, string or band 5 being wound by a complete winding, i.e. 360about the individual roll. Preferably, the crossing point 8 of thethread, string or band with the edge 4 of the end of the individualpaper web is located approximately at the central portion M of theindividual roll.

If desired, the string, thread or band may be placed around the paperroll 1 in such a way that a plurality of windings are located on asingle paper roll.

The opening of an individual paper roll according to FIG. 3 is effectedby grasping one of the ends 9 or 10, preferably the end 9, and bydetaching said string, thread or band 5 from the paper roll withouttearing the paper. It will be appreciated that when the end 9 of thethread, string or band 5 is grasped and removed in the direction of thearrow K from the paper web, the latter can be used completely withoutdestroying the same.

The detached string thread or band may be discarded through the toiletwhere they will be dissolved together with the glue, which may likewisebe water soluble.

It is, of course, to be understood, that the present invention is, by nomeans, limited to the particular construction shown in the drawing, butalso comprises any modifications within the scope of the appendedclaims.

It is also to be understood that the term thread means as it appearsherein also covers a cord, band or the like.

What I claim is:

1. A paper roll having the outer end of its paper web connected to thepaper web winding directly therebelow, which includes thread meansdetachably extending adhesively only over said outer end and said paperweb winding directly therebelow and holding the same together directlyrestrictive therebetween.

2. A paper roll according to claim 1, in which said thread means is ofwater soluble material and is connected to the paper web windingtherebelow by an adhesive limited to immediate thread periphery.

3. A paper roll according to claim 1,. in which said thread means isspirally wound over 360 at constant diameter.

4. A paper roll according to claim 2, in which said adhesive is watersoluble upon non-destructive end-winding separation.

5. A method of connecting the outer end of the paper web of a pluralityof axially joined paper rolls to the paper web winding directly belowsaid end, which includes the steps of: preparing a collective paper rollhaving a width substantially equalling n times the standard width of asingle paper roll, n being an even number, winding thread means aroundand detachably connecting the same to the thus made over-size paper rollso that said thread means passes n times over an angle of approximately360 while extending approximately from one end face of said paper rollto approximately the other end face thereof, and subsequently cuttingsaid over-size paper roll to individual paper rolls of standard width 6.A method according to claim 5, which includes the steps of so windingsaid thread means around said oversize paper roll that when the latteris cut into individual paper rolls of standard width, the thread meansobliquely cross the outer end of the paper web substantiallyapproximately halfway between the end face of each paper roll ofstandard width.
